Mobile Call Reconnection via Automatic Detection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing telecommunications systems fail to reliably reconnect calls that are unintentionally dropped due to coverage issues, often resulting in incomplete communication and increased risks for drivers trying to re-establish connections while driving.

Innovation Solution

The system implements a 'reconnect-anytime' application that detects unintentional call drops and attempts real-time reconnection, with subsequent automatic reconnection attempts when both parties regain coverage, using mobile resources and notification methods like calls, texts, or voice prompts to re-establish the call without human intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time reconnection attempts are made within a short period (e.g., five seconds), then system resources are preserved and channels are maintained, but calls dropped due to coverage issues cannot be reconnected if parties remain in blind spots

Engineering Contradiction:

Improvecall reconnection reliabilityVSAvoidtime delay for reconnection

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by detecting call drops and initiating reconnection attempts automatically. The mobile communication system detects when a call is unintentionally disconnected and proactively attempts to reestablish it without requiring user intervention, performing the reconnection action before the user would normally need to manually redial.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mobile communication system acts as an intermediary between the mobile stations and the network infrastructure. It monitors call status, detects unintentional disconnections, and coordinates reconnection attempts between base stations and mobile devices, mediating the reconnection process transparently to the users.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users manually attempt to re-establish dropped calls by dialing back the other party, then call reconnection may be achieved, but driver attention is diverted from driving and safety risks increase

Engineering Contradiction:

Improvecall reconnection capabilityVSAvoidsafety risk for drivers

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system provides self-service by automatically detecting dropped calls and initiating reconnection attempts without user involvement. The mobile communication system monitors call status, identifies unintentional disconnections, and autonomously attempts to reestablish connections, freeing users from the need to manually intervene and reducing distractions for drivers.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring call status and network conditions. When a call is dropped, the system receives feedback about the disconnection event and automatically responds with reconnection attempts, creating a closed-loop system that adapts to changing communication conditions without user input.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If extended reconnection functionality beyond real-time is implemented, then calls can be reconnected at any time after disconnection, but system complexity and resource management become more challenging

Engineering Contradiction:

Improvereconnection timing flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements dynamic reconnection behavior by adapting its reconnection attempts based on current network conditions and user availability. Rather than using a fixed reconnection timeline, the system dynamically adjusts when to attempt reconnections based on whether mobile stations are in coverage areas and whether network resources are available, making the reconnection process flexible and condition-dependent.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mobile communication system performs multiple functions: it handles normal call routing, monitors for dropped calls, detects unintentional disconnections, manages real-time reconnection attempts, and coordinates extended reconnection efforts. This multi-functional approach consolidates diverse operations within a single system framework, managing complexity through universal handling of communication tasks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Communication endpoints, including but not limited to, mobile communication devices may lose connectivity with the network mid-call. If the call does not resume relatively quickly, the system resources utilized for the call will be released and become available for other calls. However, at a later time, the inadvertently disconnected endpoint may reestablish network connectivity. By providing a system that receives a signal, such as the result of an API or polling, the reconnected endpoint is detected and the call may automatically be reestablished between the communication endpoints after the call's resources have been repurposed.
